Can I Pair Audio Reseach Ref 3 w/ the McIntosh MC2505 Poweramp?

You do have a point, I haven’t mentioned many details about my current setup. My goals here are to eventually upgrade my entire system to something much more refined and detailed, with an expansive soundstage and full bodied midrange.

Here it is:

Tannoy XT6f floorstanding speakers
Rotel RDD-1588 DAC
Blue Sound Node 2 Media Player
Rega Elex-R Integrated Amp (Preamp out)
McIntosh MC2505 Vintage Power Amp (68 WPC)
AudioQuest RCA Cables Panther

I’d Like to start my upgrades with a very capable tube preamp. I already have a system with a polished top end (which I love), and descent bottom end (could be a little tighter). I’d love to improve the soundstage depth and width, as well as the midrange response and detail.

Oh and I play high res audio only, via an external hard drive for now. Eventually including a nice record player to the mix.

Whatever you buy, you should consider the scenario if/when you upgrade your amp. I have an MC2200 McIntosh amp which may or not share the same sonic qualities as your amp and I tried it with a couple of different preamp's - mostly whatever my friends were willing to bring over and try and including my own SS NAD preamp, and the best sound was from an Audible Illusions 3A. We tried it with one of my friend's ARC LS17se and for some reason we couldn't get the volume high enough for a decently loud playback. Not sure why, probably gain mismatch. None of this will probably help with your decision since my speakers are completely different from yours- ML Aerius, and I have a huge listening room, but use the data points for whatever they're worth. All in all, there are a lot of folks out there, particularly on the McIntosh forums, that claim MAC stuff sing best when mated with other MAC components.

Yes I've heard this about Mac gear, that it stands out most when paired with other Mac gear. I hope this is true for vintage and modern combinations of Mac gear as well. But matching gain levels is another factor I hadn't considered, but now I will. I believe the c2300/ 2500 has a function that will match gain fairly accurately, someone please confirm this.

I was also considering biamping the 2505 with another 2505, and using the c2300/2500 to feed signal to both power amps (provided I decide on buying a Mac Preamp). In that scenario the pair of MC 2505's will provide over 120 WPC to each speaker.
